Binary package hint: gnome-power-manager

Currently, several Dell laptops contain Intel graphics cards. The Intel driver reports that it is able to change the display brightness, however it also reports the number of levels supported is zero.

In cases such as these, gnome power manager should fallback to the functional
HAL Backend if it's available for the laptop.

When falling back to the HAL backend, since the laptop supports the brightness changing from the HW key rather than trying to force a value change.
